N. 1 ASSIGNOB TO JABEZ BURNS & SGHS, OF NEW YORK,

ROASTER FOR COFFEE AND OTHER MATERIAL.

Specification of Letters Patent. Patented Aug". 31, l909= Application filed September 17, 1908. Serial No. 553,382.

York, in the county of New York and State of New York, have invented new and useful Improvements in Roasters for Coffee and other Materiel, of which the following is a specification.

This invention relates to a rooster for colloc and other material as for example nuts grain or the like and such roaster presents several advantages as for example easy feeding and emptying, ready starting and arresting and other features appearing in the following specification and cluims and illus trated in the annexed drawing; in which Figure 1 shows a side elevation of 21. roaster embodying this invention. Fig. 2 is a rear elevation of Fig. 1. Fig. 8 is :1 sectional side elevation of l 1. F i shows modification. Fig. is it section of the air cushion shown in Fig. l; Fig. (l is a or of the rear end of :1 modified sectional Y form of rooster shcllj In this drawing is shown it rooster proper or "hell ('1, rotzitii ely mounted in the upper section l; of e-cesing b c. vSuitable heating means for the roasteigmay be provided, but inasmuch as such forms no port of this invention. it is not, shown in the drawings. One end portion of'the shell 0: provided with. a mouth of considmrzil)le size sons to allow toreasy introduction and dumping of material, the edge or riin portion of lhe mouth being indicated at (Z. This month portion sits rototively in the corresponding mouth portion of easing Z). flhe rear wall of the shell has a shaft with gear or worm wheel a engagin a motor as presently explained. The soaft of wheel 0 extends through the rear wall of case section and said section. hinges or can swing at f on section 0. If section b swings up shell a swings therewith and can empty or dump through opening cZ. 7

When the section-b swings down or shut the worm wheel 6 carried by the shell also swings down and comes to gear or mesh with the motor mounted in section b and shown as a worm shaft g with worm 2'. As wheel 6 descends and takes worm i the resulting r0- tat'ion of the wheelturns the roaster shell a.

The roaster as seen is arranged to hold the shell a at a tilt to incline from front to rear and the shell rotates material enteringer the mouth will tend .to work to the engages." If the case tcrior of the shell (1 serve to work the mate rial forward and to thoroughly mix the some.

At the rear the worm blade can be of greater height than at the front. as the lziycr of material tends to heap up at the rear.

The roaster can be either in formoia per-.- Elorated shell for the escape of steam or van 11ers in roasting, as shown in Fig". 6, or in case l'heupperutus is to be used for fine mnter-inl which is liable to sift, the shell can be closed. and the mouth at d depended upon for the necessary escape.

The roaster or shell (1 as stated dumps when the upper section b is s'wung'up. about pivot f and a handle m can raise such rear end of the section Z1. As the roaster swings up worm wheel e 'unmeshes from its motori and on return or the roaster this wheel resection 6 should enddenly drop the genre 6 i might be injured. Jinarresting finger can prevent the dropping wheel e from slamming onto its moton 'lhis arrest-lug finger is formed by the lower or free end of a lever n fulcrumed at 0, such lower end being bent to form an l. shape. The horizontal bar of this l. entering in the space between the contact lips of section b and section 0 before they are closed these lips separated and prevents wheel e touching its motor.

The arrr ting position of the L shaped terminal is normally maintained by spring 7) between handle part 9 of lever n and the handle m and when the handles an, 9 are grasped zindpresscd together the arresting piece is withdrawn from the sections 5 c and they can be closed together 0 will again begin to rot-rite. The lever n is shown as comprising two legs or lower arms but the action is as described.

To fill theroaster a funnel roan be held to.

rear. Spirally arranged blades 7a on the inwhen the wheel keeps mouth d and withdrawn when the filling is I finished to he applied to another rooster, such roosters bein at times zirranged in series. By having alone a suitable distance with arequired number of Worms a number of roasters can be driven by such motor. The funnel 7 has its discharge spout or inlet downwardly mclined and the mouth from its edge or ridge pert flares both inwardly as also outwardly to lit the funnel discharge. A neat fitting funnel and ronid filling or feedingcan thus be obtained.

t lle motorshaft 9 extended In the modification the arresting stop 12- is replaced by an air cushion. tube or socket s is shown at or pivoted to the section b and a pistonft filling the tube isshown at section. 0. hen section b drops-or starts to slam the piston t enters and compresses the air in the tube or the tube slips over the piston and eases the closing of the sections. In

' either case a slam is prevented.

In the case of Fig. i a 'block placed between the gaping lips of sections 6 0 will hold the gear a idle if desired. At the same time excessive escape of heat from the casing 32 0 is avoided such as would occur if the casing were left entirely open. For easing the descent of the uppersection it an air cushion is used the piston 5 can have a small channel or air vent if desired. The back head of the shell a. may be perforated if desired the same as the rest of the shell as thereby less metal is contained in the shell thus absorbing less heat.

What ll claim is r 1; A roaster'tor cotlee and other mate *ial having a hollow bearing of such size as to term an opening suitable for feeding and. for 'dumping, the edge portions of said opening from the mouth outward and from said mouth inward being placed at such an angle .as to permit ready entrance for feeding, said edge portions being adapted to receive a filling funnel havin a dischar e portion made to fit the angular y placed e ge portions.

2'. A roaster for cofitee and other material comprising a shell or body portion and case made to surround and to swing with the shell to allow dumping of the contents.

3. A roaster comprising a shell and a case 1. l l l 1 witnesses.

eases? about the shell, the case being made in seetions hinged to one another, one of the sections having a rotating gear for actuating the shell, and the other section having a motor for rotating the gear.

l. A roaster comprisinga shell anda case about the shell, the case being made in sections hinged to one another, one of the sections having a rotating gear for actuating the shell and the other section having a motor for rotating the gear, said gear being made to release and rengage the motor as the sections open and close. I

A roaster comprising a shell and a case about the shell, the case being made insec tions hinged to one another, one of the sections having a rotating gear for actuating the shell and the other section having a motor for rotating the gear, said gear being made to release and reengaige the motor as the sections open and close and-an arresting device for holding the sections separated with the gear out of engagement.

A roaster comprising a shell and a case made in hinged sections, a handle at the rear of one of the sections to lift or open the section away from the other one and a spring closed lever with its handle in proximity to the other handle, said lever having an arresting piece adapted to enter between the case sections.

, In testimony whereof I have hereunto set my hand in the presence of two subscrlbing ROBERT BURNS. Witnesses:
